There are definitely some disadvantages to being the youngest of 3 (especially when the other 2 are so young), but there are also lots of perks. For example:
Disadvantage: You have to cry a lot more than your siblings did when they were babies because your mom’s busy trying to find whatever trinket Macy needs to make her friend “pirate” happy and keep your brother from base jumping off a folding chair.
Advantage: You get more snuggles once the other 2 are in bed because your mommy realizes how quickly babies grow up.
Disadvantage: Your mom has to pump (what feels to be) a zillion times a day so a bath towel or some other contraption holds your bottle.
Advantage: You are the only member of the family who has ever been allowed to watch tv while you eat.

Don’t worry Logan, there will come a time when you will probably be bigger than both of your older siblings and then you can call the shots. 😉
Advantage: You always have someone to entertain you or talk to you.
Disadvantage: There is always someone trying to talk to you or entertain you. 🙂
